[Xylina]

Hey guys,, i need some urgent help from you all guys.

I am having a Solaris System which is having some problem with its hostname. The hostname for my machine keeps coming up as "unknown". I need to change it that i don't know how to do. Could you guys please help me out in changing the hostname of my Solaris System ? Help will be appreciated.

The files that set hostname and IP address on Solaris are always in /etc,, like Solaris: /etc/inet/hosts. Like this there are 6 files that contain the hostname and you have to edit all these files. They are:

1. /etc/hosts
2. /etc/nodename
3. /etc/hostname.*
4. /etc/net/ticlts/hosts
5. /etc/net/ticots/hosts
6. /etc/net/ticotsord/hosts
7. /etc/inet/ipnodes

Once done, just reboot the system. Thats it!!

To change the hostname on a Solaris system:

1. Change the hostname in /etc/nodename. Replace the information in this file; commenting out the previous value will cause problems during a reboot.

2. Run uname -S new_hostname to change the nodename and hostname for your current session.

3. Change the hostname in /etc/hostname.network_interface (e.g., /etc/hostname.hme0). Replace the information in this file; commenting out the previous value will cause problems during a reboot.

4. Change the hostname in /etc/hosts

5. Change the hostname in /etc/net/*/hosts (/etc/net/ticlts/hosts, /etc/net/ticots/hosts, /etc/net/ticotsord/hosts), if applicable.

# for FILE in `find /etc/net -name hosts` ; do
> fgrep -l old_hostname $FILE > /dev/null 2>&1 && sed 's/old_hostname/new_hostname/g' $FILE > $FILE.new && mv $FILE.new $FILE
> done

6. Change the savecore-dir

# [ ! -d /var/crash/`uname -n` ] && mkdir /var/crash/`uname -n` && chmod 700 /var/crash/`uname -n`
# dumpadm -s /var/crash/`uname -n`

7. Change the hostname in /etc/inet/ipnodes.
